Each sequence file can contain any number of sequence file global variables. Any sequence in the file can access the sequence file global variables for the file. A subsequence can access the sequence file global variables in the sequence file that contains the calling sequence. A subsequence can also access the sequence file global variables in the process model file and in the client sequence file explicitly in an expression or in a call to the TestStand API.
The sequence context contains references to the calling sequence, the Main sequence in the client sequence file, and the Process Model entry point sequence.
Use the Sequence File Globals option on the General tab of the Sequence File Properties dialog box to specify whether TestStand creates a separate run-time copy of the sequence file globals for each execution or shares the same run-time copy of the sequence file globals.
